At least three people were arrested Tuesday during a tense anti-poverty march that ended near the Republican convention arena. Police used tear gas and flash-bang grenades to scatter protesters they said were trying to get past security fences.

At least three people were arrested Tuesday during a march against homelessness and poverty that ended near the site of the Republican convention with police firing tear gas and flash bang grenades to disperse the crowd.

A 73-year-old retired surgeon marching in silence with a tombstone picturing a soldier killed in Iraq. A philosophy professor calling for a new investigation into the Sept. 11 terrorist attacks. A long-haul trucker from Texas protesting the price of oil.

Oft-dissed Kevin Costner can't claim the same kind of retort Ben Affleck has just delivered by directing one of the year's best movies: Gone Baby Gone. Brooks is only fair. But Costner is impressive playing a Chamber of Commerce "Man of the Year" who doubles as a serial killer, even though we sometimes wish he'd ply his trade on co-star Dane Cook (and only in part because Cook's character is a creep). Say what you will, but as a cop, Demi Moore looks better at 44 than Jack Webb did.
